摘要
基于离差分析法和关联度分析法,分别研究在不同牧区不同群落的稳定性以及生态退化对群落稳定性的影响.针对生态退化程度的评价,通过对所给数据的分析和处理,利用EXCEL软件运用相对偏差模糊矩阵法、变异系数法、隶属度函数法建立模糊评价体系,得出最终评价结果.最后,建立可行性分析模型,提供恢复的改进措施的量化区间范围,并得到较为理想的结果.
In this paper, the stability of different pastoral community and ecological degradation effect on the stability of the community were studied based on the deviation analysis and correlation analysis. evaluation of ecological degradation degree, through CEL, the relative deviation of fuzzy matrix method, the analysis of the given data the variation coefficient method Aiming at the and processing, using EX- and the method of membership function in establishing fuzzy evaluation system, the final evaluation results were obtained. Finally, a feasibility analysis model was established, the quantitative range of recovery measures was provided and some ideal results were obtained.
